I think it should be possible either way - for quick edits it will be easier to manage in the timeline. For complex transitions containing multiple effect lines when we desire a higher level of control, having a seperate dialog is more useful. > And before we thnk about three track effects, there is > something much more important and maybe difficult.

I would assume that this problem goes away as soon as we can handle video and sound seperately? I think handling sound as seperate tracks on the timeline is the way to go - I cannot think of any better way to handle it :-) Except that we might want to have the ability to treat a track as Video/Audio (like we currently do) to simplify the timeline. However in this case, I would assume that the transition of sound and video would be linked together? I think that one addition that should be made to the transition picture is that there should not necessarily be only a single variable that changes within a transition - if we assume an audio/visual track for the moment, and a crossfade transition, video could have it's own crossfade 'red line', and audio could have it's own crossfade line.
